Said protective lining may comprise a plastic coating8, applied as hereinbefore described over said wire mesh. As will beclearly seen from Fig. 3, the strands of wire 1, bent alternatelyinwardly and outwardly from the plane of said interwoven points 2, tosaid points 3, will afford a greater reinforcement for said protectivelining, binding and holding the same throughout substantially its entiredepth, as illustrated in said Fig. 3 at the points 9.

It is to be understood that I have for purposes of illustration onlyshown one form of wire mesh which may be adapted to reinforce a plasticlining applied thereover. Obviously, other forms of wire mesh may beemployed, and which may be adapted to produoe the permeating effectwhich the invention affords I claim as my invention 2- 1. Incombination, a chamber having a nular heat-resistant lining on an innerwall thereof, and reinforcing means for said lining, comprising a crim dwire mesh, the

' crests and troughs of said crimps 1 ing in parallel planes and spaceda greater istance from each other than twice the diameter of said wire.

2. In combination, a vessel having a granular heat-resistant lining onan inner wall thereof, and reinforcing means for said lining comprisingin combination a wire mesh interwoven in a common plane, the unwovenstrands of said mesh being crimped and spaced in an inward and outwarddirection from said interwoven plane a distance equal to the depth ofone crimp.

3. In combination, a vessel having a granular heat-resistant lining onan inner wall thereof, and reinforcin means for said lining comprisingin combination a wire mesh interwoven in a common plane, the unwovenstrands of said mesh being crimped in an alternate inward and outwarddirection from each interwoven plane to an extent at least substantiallytwice the diameter of the wire strands com rising said mesh.

4. In com ination, a. vessel having a granular heat-resistant lining onan inner wall thereof, and reinforcing means for said lining comprisingin combination a oementitious material having imbedded therein a wiremesh, the strands comprising said mesh being crimped so that the crestsof said crimped strands are s need from the troughs of said crimps in ap ane parallel to the plane of the mesh, a distance greater than twicethe diameter of the strands comprising said mesh.

In testimony whereof I aflix my signature.
